If we need Mexican labor to harvest vegetables then institute a Bracero program which we had until 1964. No families, no illegals, no residency, no amnesty, just a worker doing work legally. Not unlike a B-1 visa program. The US farm industry was doing fine in 2019 without the current swarms of illegals which aren't coming here to harvest vegetables.illegal immigration is tied directly to the unemployment rate. When unemployment is low, immigration is high, and vice versa. With shrinking birth rates, we need immigrants, but we also need many illegal ones, so we can take advantage of them for cheap labor. It’s a disgusting truth but it’s still the truth. That is why nothing will ever get done with illegal immigration. The Deep State relies on it.
